Understanding Quantum Mechanics

For hundreds of years classical physics were taken for granted as the inalienable rules of the universe. Every visible current could be explained using the laws of gravity, kinetic velocity and more. And four-time classical physics explained everything we knew about the universe but as our technology advanced would be in a notice thing that cannot be explained using classical physics.

Quantum Physics puts everything into question. It defies every intuition we have about the natural world. It is the theory of the universe!

The observation a scientist made on the really small particles like electrons and photons. For surely different from the classical physics predicted that they would be. So the classical physics cannot explain the behavior extremely small particle.

What is Quantum?

Quantum is a Latin word for amount but in modern understanding it means the smallest possible discrete unit of any physical property, such as energy or matter.

Biggest encyclopedia on Earth Wikipedia defines Quantum as “the minimum amount of any physical entity involved in an interaction.”

What is Quantum Mechanics?

Quantum Mechanics is the branch of the physics relating to very small. But it is one of the biggest branch of the Physics.

Basically this branch deals with wave–particle duality, the mathematical description of the motion and interaction of subatomic particles, incorporating the concepts of quantization of energy, the uncertainty principle, and the correspondence principle.

Quantum mechanics is a theory that allows us to make predictions about what happens to tiny physics systems.

The wave-particle durability is the core concept of the Quantum Mechanics.

The position and momentum of a particle cannot be known to a high precision simultaneously. Consider a sine wave. In sine wave the momentum of the particle is equal to the wave length. The position of the particle is anywhere on the with a non-zero value. When you know the momentum of the particle there is only one possible wavelength for that sine wave. But that means the particle’s position cannot be known on the wave.

Measuring the position of the particle as effective superimposing many sine waves of different wavelength or each other but not with the prevision the position of the particle. It means that momentum can be wavelength any of those sine wave.

Quantum mechanics is a theoretical framework which specifies the kind of forms that physical laws must take.

In classical mechanics objects exist in a specific place at a time. But in a Quantum Mechanics objects instead exist in a haze of probability; they have a certain chance of being at point A, another chance of being at point B and so on.

The Revolutionary Principles

The quantum theory is the theoretical basis of modern physics that explains the natural and behavior of matter and energy on atomic and subatomic level.

The nature and behavior of matter and energy at that level is sometimes referred as a quantum physics and quantum mechanics. Quantum mechanics is that it is very successful as a theory, in that it is born out by experiment. But it is also responsible for the technological advances that make modern life possible. Without quantum mechanics there would be no transistor, and hence no personal computer; no laser, and hence no Blu-ray players.
